[0027] Turning ahead in the drawings, FIG. 3 illustrates a block diagram of a system 300 that can be employed for database instance container deployment. System 300 is merely exemplary and embodiments of the system are not limited to the embodiments presented herein. The system can be employed in many different embodiments or examples not specifically depicted or described herein.

As an example of an indirect manner (which also may or may not be a remote manner), a keyboard-video-mouse (KVM) switch can be used to couple the input device(s) and the display device(s) to the processing module(s) and/or the memory storage module(s). In some embodiments, the KVM switch also can be part of deployment system 310, web server 320, container level system 330, orchestration system 340, and/or display system 350. In a similar manner, the processing module(s) and the memory storage module(s) can be local and/or remote to each other.

[0031] In many embodiments, to deployment system 310, web server 320, container level system 330, orchestration system 340, and display system 350 can be configured to communicate with one or more user computers 340 and 341. In some embodiments, user computers 340 and 341 also can be referred to as customer computers and/or administrator computers. In some embodiments, deployment system 310, web server 320, container level system 330, orchestration system 340, and/or display system 350 can communicate or interface (e.g. interact) with one or more user computers (such as user computers 340 and 341) through a network or internet 330. Internet 330 can be an intranet that is not open to the public. Accordingly, in many embodiments, deployment system 310, web server 320, container level system 330, orchestration system 340, and display system 350 (and/or the software used by such systems) can represent at least a portion of a back end of system 300 operated by an operator and/or administrator of system 300, and user computers 340 and 341 (and/or the software used by such systems) can refer to a front end of system 300 used by one or more customers 350 and 351, respectively. In some embodiments, customers 350 and 351 also can be referred to as users.

[0032] Meanwhile, in many embodiments, deployment system 310, web server 320, container level system 330, orchestration system 340, and display system 350 also can be configured to communicate with one or more databases and one or more host servers 601, 602. In some embodiments, host servers 601, 602 also can be part of a back end of system 300. The one or more databases can comprise a product database that contains information about products, items, or SKUs sold by a retailer. The one or more databases can be stored on one or more memory storage modules (e.g., non-transitory memory storage module(s)), which can be similar or identical to the one or more memory storage module(s) (e.g., non-transitory memory storage module(s)) described above with respect to computer system 100 (FIG. 1). Also, in some embodiments, for any particular database of the one or more databases, that particular database can be stored on a single memory storage module of the memory storage module(s), and/or the non-transitory memory storage module(s) storing the one or more databases or the contents of that particular database can be spread across multiple ones of the memory storage module(s) and/or non-transitory memory storage module(s) storing the one or more databases, depending on the size of the particular database and/or the storage capacity of the memory storage module(s) and/or non-transitory memory storage module(s).

[0033] The one or more databases can each comprise a structured (e.g., indexed) collection of data and can be managed by any suitable database management systems configured to define, create, query, organize, update, and manage database(s). Exemplary database management systems can include MySQL (Structured Query Language) Database, PostgreSQL Database, Microsoft SQL Server Database, Oracle Database, SAP (Systems, Applications, & Products) Database, and IBM DB2 Database.

[0034] Meanwhile, communication between deployment system 310, web server 320, container level system 330, orchestration system 340, and/or display system 350, the one or more host servers 601, 602, and/or the one or more databases can be implemented using any suitable manner of wired and/or wireless communication. Accordingly, system 300 can comprise any software and/or hardware components configured to implement the wired and/or wireless communication. Further, the wired and/or wireless communication can be implemented using any one or any combination of wired and/or wireless communication network topologies (e.g., ring, line, tree, bus, mesh, star, daisy chain, hybrid, etc.) and/or protocols (e.g., personal area network (PAN) protocol(s), local area network (LAN) protocol(s), wide area network (WAN) protocol(s), cellular network protocol(s), powerline network protocol(s), etc.). Exemplary PAN protocol(s) can comprise Bluetooth, Zigbee, Wireless Universal Serial Bus (USB), Z-Wave, etc.; exemplary LAN and/or WAN protocol(s) can comprise Institute of Electrical and Electronic Engineers (IEEE) 802.3 (also known as Ethernet), IEEE 802.11 (also known as WiFi), etc.; and exemplary wireless cellular network protocol(s) can comprise Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Evolution-Data Optimized (EV-DO), Enhanced Data Rates for GSM Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), Digital Enhanced Cordless Telecommunications (DECT), Digital AMPS (IS-136/Time Division Multiple Access (TDMA)), Integrated Digital Enhanced Network (iDEN), Evolved High-Speed Packet Access (HSPA+), Long-Term Evolution (LTE), WiMAX, etc. The specific communication software and/or hardware implemented can depend on the network topologies and/or protocols implemented, and vice versa.

[0035] Turning ahead in the drawings, FIG. 4 illustrates a flow chart for a method 400, according to an embodiment. Method 400 is merely exemplary and is not limited to the embodiments presented herein. Method 400 can be employed in many different embodiments or examples not specifically depicted or described herein. In some embodiments, the activities of method 400 can be performed in the order presented. In other embodiments, the activities of method 400 can be performed in any suitable order. In still other embodiments, one or more of the activities of method 400 can be combined or skipped. In many embodiments, system 300 (FIG. 3) can be suitable to perform method 400 and/or one or more of the activities of method 400. In these or other embodiments, one or more of the activities of method 400 can be implemented as one or more computer instructions configured to run at one or more processing modules and configured to be stored at one or more non-transitory memory storage modules, such as modules 512, 532, 534, 542, 544, 552 (FIG. 5). Such non-transitory memory storage modules can be part of a computer system such as deployment system 310 (FIGS. 3 & 5), container level system 330 (FIGS. 3 & 5), orchestration system 340 (FIGS. 3 & 5), and/or display system 350. The processing module(s) can be similar or identical to the processing module(s) described above with respect to computer system 100 (FIG. 1).

[0036] Method 400 can comprise an activity 405 of cabling a plurality of host servers for network aggregation. For example, host servers 601, 602 (FIGS. 5 & 6) can be cabled for network aggregation. Other embodiments contemplated herein may comprise any number of a plurality of host servers or, alternatively, a single host server. In many embodiments, host servers can include the necessary specifications to support running multiple containers and application instances at the respective host server. In some embodiments, the plurality of host servers can comprise a server farm created from a plurality of racks. In some embodiments, the host network of the plurality of host servers is designed with leaf-spine network topology.

[0037] Method 400 also can comprise an activity 410 of allocating a pool of internet protocol (IP) addresses to each host server. More particularly, using FIG. 6 as an example, a method can comprise allocating a first pool 611 of a first plurality of IP addresses to a first host server 601, and allocating a second pool 612 of a second plurality of IP addresses to a second server 602. For example, the non-limiting block diagram of FIG. 6 shows a system 600 having a first server 601, which comprises a first pool 611 of IP addresses, and also having a second server 602, which comprises a second pool 612 of IP addresses. In some embodiments, the first plurality of IP addresses in the first pool 611 at the first server 601 are different from and non-overlapping with the second plurality of IP addresses of the second pool 612 at the second server 602. In some embodiments, each host server is allocated with at least two IP addresses in the pool of IP addresses. The pool of IP addresses can comprise a pool of physical IP addresses and/or a pool of routable IP addresses. In some embodiments comprising a pool of routable IP addresses, there is no virtual network layer on the host server that is responsible to direct server traffic. IP addresses can be assigned directly to the bonded network interface or to multiple aliases created on the server.

[0038] Returning to FIG. 4, method 400 can further comprise an activity 415 of creating a bonded network interface at a host server. More particularly, using FIG. 6 as an example, a method can comprise activities of creating a first bonded network interface 621 at the first host server 601 and creating a second bonded network interface 622 at the second host server 602. For example, the non-limiting block diagram of FIG. 6 shows a first bonded network interface 621 created at the first host server 601 and a second bonded network interface 622 created at the second host server 602. Thus, in some embodiments, a first host server of a server network can comprise a bonded network interface and a first plurality of internet protocol (IP) addresses in a first pool of IP addresses, and a second host server of the server network can comprise a bonded network interface and a second plurality of IP addresses in a second pool of plurality of IP addresses.

[0039] In some embodiments, creating the bonded network interface for the respective host server comprises aggregating a plurality of network interface controllers (NIC) available at the host server in active-active mode. For example, in active-active mode, all the network interfaces in a bonded network interface are actively servicing network traffic. Different embodiments can utilize different implementations of active mode, such as but not limited to a first active-active mode, a second active-active mode, a third active-active mode, a fourth active-active mode, a fifth active-active mode, a sixth active-active mode, and a seventh active-active mode. A first active-active mode can comprise a balanced round robin. For example, if there are three physical interfaces in the bonded network interface, the first frame will go out to the first interface of the bonded network interface, the second frame will go out to the second interface of the bonded network interface, and the third frame will go out to the third interface of the bonded network interface. In a second active-active mode, when an active interface face fails, the next active interface in line in the bonded network interface can be used for transmitting. In a third active-active mode, or XOR mode, the same active interface always can be selected for the same destination media access control (MAC) address. In a fourth active-active mode, or broadcast mode, everything can be transmitted to all active interfaces. In a fifth active-active mode, or dynamic link aggregation, the active interface can have the same link speed and duplex settings. Active interface selection in a fifth active-active mode can be done based on the hash policy or the XOR policy of the third active-active mode. A sixth active-active mode can be adaptive transmit load balancing, and can be done based on the present load on the active interfaces of the bonded network interface. The active interfaces under a lesser outgoing queue can be chosen. A seventh active-active mode can be similar to the sixth active-active mode, with the possible addition of receiving load balance. It is noted that various embodiments contemplated herein can utilize any of the described active-active modes. Furthermore, network bonding can require certain conditions to be met at the switch level. Thus, the switch to which the bonded network interface is coupled can support the specific active-active mode being utilized in the system.

[0040] In some embodiments, all of the available NICs at a host server may be aggregated to create the bonded network interface at that host server. More particularly, creating the first bonded network interface at the first host server can comprise creating the first bonded network interface by aggregating a plurality of network interface controllers available in the first host server when the first host server is in an active-active mode, and creating the second bonded network interface at the second host server can comprises creating the second bonded network interface by aggregating a plurality of network interface controllers available in the second host server when the second host server is in an active-active mode. By creating a bonded network interface with the host server in active-active mode, maximum network bandwidth for high throughput and availability on the host server is achieved. It is contemplated, however, that other modes also may be utilized in other embodiments, such as but not limited to aggregating a plurality of network interface controllers available in the host server when the host server is in an active-passive mode.

[0041] Returning back to FIG. 4, method 400 also can comprise an activity 420 of receiving a request from an input device to deploy or otherwise create a database instance container at a host server. In more particular embodiments, a method can comprise receiving a request from an input device to deploy one or more database instance containers at a first host server, and a request from the input device to deploy one or more of database instance containers at a second host server. For example, a method can comprise receiving a request from an input device to deploy one or more of a first database instance container and a third database instance container at a first host server, and receiving a request from the input device to deploy one or more of a second database instance container and a fourth database instance container at a second host server. In some embodiments, the input device can determine whether the first host server and the second host server are in the same or separate fault zones. The input device can be one of the input devices of the system 300 (FIG. 3) or one of user computers 340, 341 (FIG. 3). In some embodiments, using FIG. 5 as an example, deployment module 512 of deployment system 310 of system 300 receives a request from an input device to deploy or otherwise create a database instance container at a host server. In other embodiments, any other modules 532, 534, 542, 544, 552 of system 300 can receive a request from an input device to deploy or otherwise create a database instance container at a host server.

[0042] Referring to FIG. 4, again, method 400 also can comprise an activity 425 of transmitting an instruction from an output device to deploy or otherwise create a database instance container at a host server. In more particular embodiments, a method can comprise transmitting an instruction from an output device to deploy one or more database instance containers at a first host server on a host server network responsive to the request from the input device, and transmitting an instruction from the output device to deploy one or more database instance containers at a second host server network responsive to the request from the input device. For example, a method can comprise transmitting an instruction from an output device to deploy the one or more of the first database instance container and the third database instance container at the first host server responsive to the request from the input device, and transmitting an instruction from the output device to deploy the one or more of the second database instance container and the fourth database instance container at the second host server responsive to the request from the input device. The output device can be one of the output devices of the system 300 (FIG. 3) or user computers 340, 341 (FIG. 3). In some embodiments, using FIG. 5 as an example, deployment module 512 of deployment system 310 of system 300 is configured to transmit instructions to the output device to deploy or otherwise create a database instance container at a host server of a host server network. In other embodiments, any other modules 532, 534, 542, 544, 552 of system 300 can transmit instructions to the output device to deploy or otherwise create a database instance container at a host server of a host server network.

[0043] Referring back to FIG. 4, method 400 can further comprise an activity 430 of creating a database instance container at the host server. As used herein, a database instance container can comprise an application instance container. As such, a database instance container can comprise an application or database deployed within a container on a host server. In more particular embodiments, a method can comprise an activity of creating a plurality of database instance containers at a first host server of a host server network and a plurality of database instance containers at a second host server of the host server network. In some embodiments, creating the database instance container at a host server comprises installing a database on the first host server, and then creating a container at the first host server by using one IP address from the pool of IP addresses of the host server to create a network alias on the bonded network interface at the host server. A routable IP address from the pool of IP addresses can be assigned to the network alias. After the container is created, an installation path of the database can be mapped to a directory inside the container such that the database can then be started inside the container. In particular embodiments comprising a plurality of host servers, a method can comprise creating the first database instance container at the first host server by using one IP address from the first pool of the first plurality of IP addresses of the first host server to create a first virtual IP address on the first bonded network interface at the first host server, and creating the second database instance container at the second host server by using one IP address from the second pool of the second plurality of IP addresses of the second host server to create a second virtual IP address on the second bonded network interface at the second host server.

[0044] Turning to FIG. 5, in some embodiments, deployment module 512 of deployment system 310 of system 300 creates a database instance container at the host server. In other embodiments, any other modules 532, 534, 542, 544, 552 of system 300 can create a database instance container at the host server. In some embodiments, database instance containers can be deployed using Dockers or other container services. In some embodiments, systems and methods can comprise virtual network interface on top of the bonded network interface for every database instance container. The virtual IP addresses can belong to the same virtual local area network (VLAN) or a different VLAN depending upon the desired security requirements. Each database instance container created can be created with predetermined required system resources, such as but not limited to CPU and memory.

[0045] In some embodiments, creating a database instance container at a host server can comprise creating a database instance container belonging to a cluster at a host server. In more particular embodiments, multiple database instance containers created or otherwise deployed at a host server may belong to different and non-overlapping clusters. For example, a method can comprise deploying a first database instance container at a first host server, the first database instance container belonging to a first cluster, deploying a second database instance container at a second host server, the second database instance container belonging to the first cluster, deploying a third database instance container at the first host server, the third database instance container belonging to the first cluster, and deploying a fourth database instance container at the second host server, the fourth database instance container belonging to the second cluster. The first cluster and the second cluster of such embodiments can be different from and non-overlapping with one another. The non-limiting block diagram of FIG. 6 shows, by way of example, a first database instance container (D.I.C.) 651 of a first cluster 641 at a first host server 601, a second database instance container 652 of a second cluster 642 at the first host server 601, a third database instance container 653 of the first cluster 641 at a second host server 602, and a fourth database instance container 654 of the second cluster 642 at the second host server 602.

[0046] By distributing database instance containers of a cluster to different host servers, system performance is improved in case of a crash or other hardware malfunction of the host server. Some embodiments can be designed to be rack or fault domain aware. Thus, clusters can be created with nodes or database instance containers in different fault tolerant zones. If a host server or other hardware has a malfunction, then the malfunction results in only the loss of the database instance container running on the host server or hardware, and does not result in the loss of the entire cluster. Moreover, by deploying multiple database instance containers on a single host server, the capacity for database instances can be doubled (or more), thereby saving costs for the administrator.

[0047] Returning to FIG. 4, method 400 can further comprise an activity 435 of binding the database instance container to the bonded network interface and also a first IP address from the pool of IP addresses of the host server. Thus, the database deployed inside the container has direct access to the host level system, storage, and network resources. In some embodiments, binding the database instance container to the IP address of the host server comprises binding the database instance container to a physical IP address of the host server. More particularly, a method can comprise binding the database instance container to a bonded network interface and also to a first IP address of the pool of IP addresses of the host server of the host server network such that a database deployed inside the database instance container has direct access to the host server. In embodiments comprising a plurality of host servers and database instance containers, a method can comprise the activities of binding a first database instance container to the first bonded network interface and also to a first IP address of the first pool of the first plurality of IP addresses of the first host server such that a first database deployed inside the first database instance container has direct access to the first host server, and binding a second database instance container to the second bonded network interface and also to a second IP address of the second pool of the second plurality of IP addresses of the second host server such that a second database inside the second database instance container has direct access to the second host server.

[0048] Deployment of database instance container by binding the database instance container to a bonded network interface and also an IP address of the host server is advantageous because this deployment enables the database deployed within the database instance container to have direct access to the system resources and avoid any resource virtualization. Referring to FIG. 5, in some embodiments, deployment module 512 of deployment system 310 of system 300 binds the database instance container to the bonded network interface and also to a first IP address from the pool of IP addresses of the host server. In other embodiments, any other modules 532, 534, 542, 544, 552 of system 300 can bind the database instance container to the bonded network interface and also to a first IP address from the pool of IP addresses of the host server. In some embodiments, each IP address bound to a database instance container can be assigned with an addressable hostname and/or public name.

[0049] In some embodiments, binding the database instance container to an IP address from the pool of IP addresses of the host server can comprise allocating the IP address from the pool of IP addresses of the host server to a database instance container. In more particular embodiments, allocation of the IP address from the pool of IP addresses of the host server can be automatic or otherwise automated. For example, a method can comprise automatically allocating a first IP address of the first host server to the first database instance container, automatically allocating a second IP address of the second host server to the second database instance container, automatically allocating a third IP address of the first host server to the third database instance container, automatically allocating a fourth IP address of the second host server to the fourth database instance container, and automatically allocating an additional IP address of either one of the first host server or the second host server to an additional database instance container for binding to the respective host server. In some embodiments, allocation module 544 of orchestration system 340 is configured to automatically allocate an IP address of a host server to a database instance container. In other embodiments, any other modules 532, 534, 542, 544, 552 of system 300 can automatically allocate the IP address from the pool of IP addresses of the host server to a database instance container. In some embodiments, automatic allocation of an IP address of a pool of IP addresses can be based up on the availability of the IP addresses in the pool of the IP addresses of the particular host server. Orchestration tools developed using products such as Chef, Jenkins, Github, and Rundeck can be utilized to automate deployment of database instance containers.

[0050] As referenced above, some embodiments can comprise a plurality of clusters, a plurality of database containers, and a plurality of host servers. In these and other embodiments, binding the database instance container to an IP address from the pool of IP addresses of the host server can comprise binding the first database instance container of the first cluster to a first IP address of the first plurality of IP addresses of the first host server such that a first database deployed inside the first database instance container has direct access to the first host server, binding the second database instance container of the first cluster to a second IP address of the second plurality of IP addresses of the second host server such that a second database deployed inside the second database instance container has direct access to the second host server, binding the third database instance container of the second cluster to a third IP address of the first plurality of IP addresses of the first host server such that a third database deployed inside the third database instance container has direct access to the first host server, and binding the fourth database instance container of the second cluster to a fourth IP address of the second plurality of IP addresses of the second host server such that a fourth database deployed inside the fourth database instance container has direct access to the second host server.

[0051] Continuing with FIG. 4, method 400 can further comprise an activity of limiting an amount of a central processing unit (CPU) allocated to each database instance container. For example, a method can comprise limiting one or more different or same amounts of a CPU of the system allocated to each of the first, second, third, and fourth database instance containers. When creating a container on the host server, the container instance is allocated a specific number of CPU cores. If the container malfunctions and consumes excessive amounts of CPU capacity, the container could never consume more than what is allocated to the container. Referring to FIG. 5, in some embodiments, a CPU module 532 of the container level system 330 is configured to limit an amount of a CPU allocated to each database instance container. In other embodiments, any other modules 512, 534, 542, 544, 552 of system 300 can be configured to limit an amount of a CPU allocated to each database instance container.

[0052] Method 400 of FIG. 4 can further comprise an activity of guaranteeing an amount of a CPU allocated to each database instance container. For example, a method can comprise an activity of guaranteeing one or more different or same amounts of the CPU of the system allocated to each of the first, second, third, and fourth database instance containers. Referring to FIG. 5, in some embodiments, a CPU module 532 of the container level system 330 is configured to guarantee an amount of a CPU allocated to each database instance container. In other embodiments, any other modules 512, 534, 542, 544, 552 of system 300 can be configured to guarantee an amount of a CPU allocated to each database instance container.

[0053] Method 400 of FIG. 4 can further comprise an activity of limiting an amount of memory of the system allocated to each database instance container. For example, a method can comprise an activity of limiting one or more different or same amounts of memory of the system allocated to each of the first, second, third, and fourth database instance containers. Limiting the amount of memory allocated to each database instance container can be advantageous to the system. For example, a memory leak in the database running inside the container will not affect the other containers on the same host server by consuming all the system memory. Referring to FIG. 5, in some embodiments, a memory module 534 of the container level system 330 is configured to limit an amount of memory allocated to each database instance container. In other embodiments, any other modules 512, 532, 542, 544, 552 of system 300 can be configured to limit an amount of memory allocated to each database instance container.

[0054] Method 400 of FIG. 4 can further comprise an activity of guaranteeing an amount of memory of the system allocated to each database instance container. For example, a method can comprise guaranteeing one or more different or same amounts of the memory of the system allocated to each of the first, second, third, fourth database instance containers. Referring to FIG. 5, in some embodiments, a memory module 534 of the container level system 330 is configured to guarantee an amount of a memory allocated to each database instance container. In other embodiments, any other modules 512, 532, 542, 544, 552 of system 300 can be configured to guarantee an amount of a memory allocated to each database instance container.

[0055] Method 400 of FIG. 4 can further comprise an activity 440 of mapping a persistent file system. Mapping the persistent file system can comprise mapping a persistent file system for each host server to host level volumes. In some embodiments, each host server can comprise multiple file system partitions. In such embodiments, a full partition to a container can be mapped such that a container will be able to see all the files on the file system. Alternatively, different directories on a file system can be created, and a directory can be mapped to the container such that a container will be able to see all the files within that specific directory. In some embodiments, mapping a persistent file system for each host server to host level volumes can comprise mapping a directory structure inside the container such that a volume of the directory structure inside the container is mapped to a directory and/or partition outside the container. For example, a method can comprise an activity of mapping a first persistent file system of a first host server to a predetermined first host level volume, and mapping a second persistent file system of the second host server to a predetermined second host level volume. Referring to FIG. 5, in some embodiments, an orchestration module 542 of the orchestration system 340 is configured to map a persistent file system of each host server. In other embodiments, any other modules 512, 532, 534, 544, 552 of system 300 can be configured to map a persistent file system of each host server.

[0056] Method 400 of FIG. 4 can further comprise an activity 445 of storing data of a database instance container outside the database instance container and in the persistent file system. For example, a method can comprise storing application data of a first database instance container in a first persistent file system of a first host and outside the first database instance container, storing application data of a second database instance container in a second persistent file system of a second host server and outside the second database instance container, storing application data of a third database instance container in the first persistent file system of the first host and outside the third database instance container, and storing application data of a fourth database instance container in the second persistent file system of the second host server and outside the fourth database instance container. The non-limiting block diagram of FIG. 6 illustrates, by way of example, a first persistent file system 631 at a first host server 601 outside the database instance containers of the first host server 601, and a second persistent file system 632 at a second host server 602 outside the database instance containers of the second host server 602. Referring to FIG. 5, in some embodiments, an orchestration module 542 of the orchestrations system 340 is configured to store data of a database instance container outside the database instance container and in the persistent file system. In other embodiments, any other modules 512, 532, 534, 544, 552 of system 300 can be configured to store data of a database instance container outside the database instance container and in the persistent file system.

[0057] In some embodiments, storing data of a database instance container outside the database instance container and in the persistent file system comprises storing all data of the database instance container outside the database instance container and in the persistent file system. As used herein, all data references components of a particular database instance container deployment, the data files, the log files, and any other data that needs to be persisted. Storing data of the database instance container outside the database instance container and in a persistent file system is advantageous to virtual machines, which use ephemeral storage that is susceptible to data loss. Moreover, storing components of a particular database container deployment outside the database instance container is advantageous because any change to the specific deployment configuration of the database instance container does not warrant rebuilding of the container images.

[0058] Method 400 can further comprise an activity 450 of facilitating a display on a device of the host server at which the database instance container has been deployed. In some embodiments, a user interface communicates to an application programming interface (API) exposed on all the host servers to retrieve (a) information on the containers that each host server is running and (b) the specifications of the host server and the containers operating thereon. For example, a method can comprise activities of facilitating a display on a device of the first host server at which one or more of the first database instance container and the third database instance container has been deployed, and facilitating a display on a device of the second host server at which one or more of the second database instance container and the fourth database instance container has been deployed. In some embodiments, a display module 552 of the display system 550 is configured to facilitate a display on a device at the host server at which the database instance container has been deployed. In other embodiments, any other modules 512, 532, 534, 542, 544 of system 300 can be configured to facilitate a display on a device at the host server at which the database instance container has been deployed.

[0059] In some embodiments, method 400 also can comprise an activity of facilitating a display on a device of a user interface configured to capture requirements of a database instance container, monitor host servers and clusters, and allow a user or administrator to configure clusters, host servers, and database instance containers. Examining FIG. 5, in some embodiments, a display module 552 of the display system 550 is configured to facilitate a display on a device of a user interface. In other embodiments, any other modules 512, 532, 534, 542, 544 of system 300 can be configured to facilitate a display on a device of a user interface.

[0060] Returning to FIG. 4, method 400 also can comprise an activity 455 of eliminating or removing a database instance container from a host server. For example, a method can comprise eliminating at least one of the first database instance container or the second database instance container from a host server.

[0061] Upon elimination of a database instance container, method 400 can comprise activities 460 of deallocating an IP address from a database instance container and returning the IP address to the pool of IP addresses of the host server. In more particular embodiments, a method can comprise the activities of automatically deallocating a first IP address of the first host server to the first database instance container, automatically deallocating a second IP address of the second host server to the second database instance container, automatically deallocating a third IP address of the first host server to the third database instance container, automatically deallocating a fourth IP address of the second host server to the fourth database instance container, and automatically deallocating an additional IP address of either one of the first host server or the second host server from an additional database instance container at the respective host server. Upon deallocation of an IP address to a database instance container, the IP address may be returned to the pool of IP addresses of the host server to which the database instance container had previously been bound. For example, if a first database instance container is eliminated, a method can comprise returning the first IP address of the first database instance container to the first pool of the first plurality of IP addresses of the first host server, and if a second database instance container is eliminated, a method can comprise returning the second IP address of the second database instance container to the second pool of the second plurality of IP addresses of the second host server.

[0062] Returning to FIG. 5, in some embodiments, allocation module 544 of orchestration system 340 is configured to automatically deallocate an IP address of a host server to a database instance container. In other embodiments, any other modules 532, 534, 542, 544, 552 of system 300 can automatically deallocate the IP address from the pool of IP addresses of the host server to a database instance container.

[0063] Method 400 in FIG. 4 can further comprise an activity of selecting one host server of the first host server or the second host server for binding of at least one additional database instance container to an IP address of the one of the first host server or the second host server based upon at least one of the one or more of (a) resource availability of the first host server relative to the second host server or (b) a number of database instance containers already bound to the first host server relative to the second host server. In some embodiments, selecting a host server for binding of a database instance container is determined by a set of rules and/or an algorithm. Turning to FIG. 5, in some embodiments, orchestration module 542 of orchestration system 340 comprises information about all the switches in the network and is configured to obtain port number/mac address information of all of the switches in the network. In a container configuration, a particular IP address of the host server can be defined to be assigned or allocated to a database container instance. Before assigning or allocating the IP address to the database instance container, the orchestration system 340 can determine which host server has capacity to run that database instance container. The orchestration system 340 can then log into the switch where one of the physical NICs is coupled, configure the VLAN on that switch port, and start container binding the VLAN to the NIC with the IP provided. Thus, no virtual network layer is utilized.

[0064] Returning to FIG. 4, method 400 can further comprise an activity 465 of determining if a host server has sufficient space to create a redundant array of independent discs (RAID). More particularly, a method can comprise specifying an amount of storage space required for an additional database instance container and determining which one host server of the first host server and the second host server has sufficient space to create a RAID volume.

[0065] Method 400 can further comprise an activity 470 deploying an additional database container. For example, upon determining which host server has sufficient space to create a RAID volume, a method can comprise deploying an additional database instance container to the one host server of the first host server or the second host server determined to have sufficient space to create the RAID volume. In more particular embodiments, deploying an additional database container can comprise deploying an additional database instance container to a cluster if utilization of the cluster exceeds a defined threshold. For example, deploying an additional database cluster can comprise deploying a first additional database instance container to the first cluster if utilization of the first cluster exceeds a defined threshold, and deploying a second additional database instance container to the second cluster if utilization of the second cluster exceeds the defined threshold. Reviewing FIG. 5, in some embodiments, deployment module 512 of the deployment system 310 is configured to deploy an additional database container. In other embodiments, any other modules 532, 534, 542, 544, 552 of system 300 can be configured to deploy an additional database container. While these deployments of database instance containers are described with respect to additional database instance containers, it also is contemplated that similar activities can be performed for deployment of any database instance containers, including but not limited to a first database instance container deployed to or otherwise created at a first host server.

[0066] Method 400 in FIG. 4 can further comprise an activity 470 of eliminating an additional database instance container. Eliminating an additional database instance container can comprise eliminating the additional database instance if utilization of the cluster to which the database instance container belongs falls below a defined threshold. For example, a method can comprise eliminating a first additional database instance container from a first cluster if utilization of the first cluster falls below the defined threshold, and/or eliminating a second additional database instance container from a second cluster if utilization of the second cluster falls below the defined threshold. Returning to FIG. 5, in some embodiments, deployment module 512 of the deployment system 310 is configured to eliminate an additional database container. In other embodiments, any other modules 532, 534, 542, 544, 552 of system 300 can be configured to eliminate an additional database container. While these embodiments are described with respect to additional database instance containers, it also is contemplated that similar activities can be performed for deployment of any database instance containers, including but not limited to a first database instance container deployed to or otherwise created at a first host server.

[0067] FIG. 5 illustrates a block diagram of a portion of system 300 comprising deployment 310, container level system 330, orchestration system 340, and display system 350 according to the embodiment shown in FIG. 3. Each of deployment 310, container level system 330, orchestration system 340, and/or display system 350 is merely exemplary and not limited to the embodiments presented herein. Each of deployment 310, container level system 330, orchestration system 340, and/or display system 350 can be employed in many different embodiments or examples not specifically depicted or described herein. In some embodiments, certain elements or modules of deployment 310, container level system 330, orchestration system 340, and/or display system 350 can perform various procedures, processes, and/or acts. In other embodiments, the procedures, processes, and/or acts can be performed by other suitable elements or modules.

[0068] In many embodiments deployment system 310 can comprise a non-transitory storage module such as module 512, container level system 330 can comprise non-transitory storage modules such as modules 532, 534, orchestration system 340 can comprise non-transitory storage modules such as modules 542, 544, and display system 350 can comprise a non-transitory storage module such as module 552. Module 512 can be referred to as deployment module 512, module 532 can be referred to as CPU module 532, module 534 can be referred to as memory module 534, module 542 can be referred to as orchestration module 542, module 544 can be referred to as allocation module 544, and module 552 can be referred to as display module 552.

[0069] In many embodiments, deployment module 512 can store computing instructions configured to run on one or more processing modules and perform one or more acts of method 400 (FIG. 4) (e.g. activity 420 of receiving a request from an input device to deploy a database instance container at the host server, activity 425 of transmitting an instruction from an output device to deploy the database instance container at the host server, activity 430 of creating a database instance container at the host server, and activity 435 of binding the database instance container to the bonded network interface and also an IP address from the pool of IP addresses of the host server). In some embodiments, CPU module 532 can store computing instructions configured to run on one or more processing modules and perform one or more acts of a method (e.g. an activity of guaranteeing and/or limiting an amount of CPU of the system allocated to each database instance container). In some embodiments, memory module 534 can store computing instructions configured to run on one or more processing modules and perform one or more acts of a method (e.g. an activity of guaranteeing and/or limiting an amount of memory of the system allocated to each database instance container). In some embodiments, orchestration module 542 can store computing instructions configured to run on one or more processing modules and perform one or more acts of method 400 (FIG. 4) (e.g. activity 440 of mapping a persistent file system and activity 445 storing data of the database instance container outside the database instance container and in the persistent file system). In some embodiments, allocation module 544 can store computing instructions configured to run on one or more processing modules and perform one or more acts of a method (e.g. allocating and deallocating an IP address of a host server to a database instance container). In some embodiments, display module 552 can store computing instructions configured to run on one or more processing modules and perform one or more acts of method 400 (FIG. 4) (e.g. activity 450 of facilitating a display on a device of the host server at which the database instance container has been deployed).

[0070] In some embodiments, orchestration system can comprise a VLAN orchestration module. The VLAN orchestration module, or any other modules 512, 532, 534, 542, 544, 552, can be configured to configure VLANs on the switch to which the host servers are coupled. The VLAN orchestration module can be configured to automatically detect a fleet of switches coupled to a cluster and, based on the requirement, configure switch ports of the VLAN depending upon which database instance container is going to run on the bare metal host coupled to that switch port.

[0071] Various embodiments described herein allow a user to deploy multiple database instance containers to optimally leverage system resources, which results in reducing the overall hardware procurement costs, extending the available capacity of the system, and lowering of the effective license costs. Some embodiments provide the efficiency of a bare metal system while simultaneously avoiding the inefficiency of virtualized system caused by resource virtualization layers. For example, some embodiments described herein are devoid of a virtualization layers between the host server and the database instance container.

[0072] To illustrate the efficiency of the contemplated embodiments, performance tests were completed. The performance test environment included a production cluster on bare metal and a database instance container cluster (using production hardware). The test was performed by an application "e-Receipts". All clusters were created with four nodes in each of two datacenters for a total of eight nodes. Cassandra applications were utilized across the test environments, and the configurations/setup of the Cassandra applications was similar across the test environments. A test load was continuously executed from four application instances, two from each data center, accessing the local datacenter nodes. Each application instance wrote/read 1,000,000 rows. Table 1 provides a summary of a test environment configuration of the performance test.

[0073] Table 2 provides a number comparison of the performance test of the e-Receipts application on the bare metal and database instance containers systems. The asterisk in Table 2 notes that a difference in I/O throughput was caused by the different storage RAID configurations. The results of the performance testing indicate that the database instance container solution performs similar to bare metal systems.
